Call me Obsessive if you like

Call me Obsessive if you like - This morning I was emptying the dishwasher and putting away these cups. Four lovely cup patterns we have purchased from the National Trust over the last year (ish). Now I have to have them in patterned collections and I cannot see anything wrong with this but others find it extremely funny. Not sure if they mean 'Funny Ha Ha' or 'Funny Peculiar'
